I am afraid boost/io/format will be confusing in a sight of presence of
Boost.Format.
I would prefer (since it all about container output formatting)

boost/io/container

Also it could be stl instead of std, though it's the matter of taste.

I personally would really prefer verbose format specification. So I should
not remember what each of the parameters means by it's position.
Something along this lines:

std::cout << start_elelment<value_type>( "[" ) // if you need value
type_here. I am not sure
              << end_element<value_type>( "]\n" )
              << element_delimeter<value_type>( " => " )
              ...
              << values;

Or

std::cout << format<value_type>().start_elelment( "[" ).end_element( "]\n"
).delimeter( " => " )
              ...
              << values;

Or mix of this styles. Or - the very best - all of them.
